Immense Circular Terrestrial Structures Of Great Age

J.M. Saul has analyzed many topographic and geological maps and discovered faint circular terrestrial patterns that have mostly not been described before. These circles measure between 7 and 700 kilometers in diameter and are nearly perfect geometrical figures. The rims of the circles are generally raised and characterized by fracturing and brecciation. These structures can be traced in many geological environments and rocks of all ages. They control to an extraordinary extent regional geology and ore mineralization.

To date, some 1,170 circles have been discovered, of which more than half can be visually traced for 360�. Larger circles may exist; one with a diameter of about 2,200 kilometers seems to encircle the southern end of Africa. In the United States, the centers of the circles fall in a northwesterly trend in Arizona; northeasterly in the Appalachians. These circular structures may have been created about 4 billion years ago by intense meteorite bombardment similar to and perhaps identical with the bombardment that marked the surfaces of the moon and other inner planets.
